15 Iconic Animal Sidekicks And Mascots In Anime
Pika pika! Scene starts, heroes talk, and then little buddy shows up and steals everything, pika.
Fluffy, sneaky, sometimes flying, always adorable, these sidekicks zap all the attention without even trying.
Hearts get captured, fans go “aww,” and suddenly nobody remembers the main character, just the cute one, pikaaa.
1. Pikachu – Pokémon
First thunderbolt moment hooked an entire generation. Face of Pokémon stands among the most recognized characters on the planet.
Bond shared with Ash reads less like trainer and pet and more like two best friends taking on the world one gym badge at a time.
Stubborn, loyal, and absolutely electric, Pikachu proves the smallest teammate can carry the biggest heart.
2. Luna – Sailor Moon
Walking into a room, Luna instantly gives the impression that every life choice you have ever made is being quietly judged, and somehow that feels reassuring.
As Usagi’s wise and occasionally exasperated guide, Luna helps launch and shape the Sailor Moon mission from the very beginning. A crescent moon on her forehead and ancient wisdom in her eyes make Luna proof that the best mentors come in unexpected packages.
3. Happy – Fairy Tail
Few sidekicks can match Happy’s talent for dropping a perfectly timed “Aye, sir!” right when the mood needs lifting.
This little blue Exceed from Fairy Tail is Natsu’s closest companion and one of the series’ most reliable mood-lifters. Full emotional journey begins the moment Happy shows up on screen during a calm Tuesday morning Fairy Tail binge.
Small wings, big feelings, zero filter.
4. Ein – Cowboy Bebop
Smartest presence on the Bebop comes with four legs, and everyone on board knows it, including Ein.
Modified Pembroke Welsh Corgi operates as a data dog with enhanced intelligence, rarely making a sound while consistently outthinking the humans around him.
Lazy Saturday energy settles in with jazz playing somewhere nearby, while a corgi watches from across the couch, quietly judging every questionable snack choice. Cool, quiet competence shows up wrapped in the fluffiest possible package.
5. Akamaru – Naruto
Akamaru grows from a puppy into a formidable ninja hound, while his bond with Kiba stays central throughout the series.
Years of missions and near misses shaped a bond built entirely on trust, the kind that never needs explaining.
Side by side, both move like a single instinct, reacting before words ever have a chance to catch up. Watching it unfold, every dog owner felt personally seen.
6. Kirara – InuYasha
By day, a tiny adorable kitten you could cradle in one hand.
In battle, Kirara transforms into a larger fiery demon cat capable of carrying allies across the landscape. Kirara belongs to Sango and serves as transport, battle partner, and stress-relief fluff all in one remarkably compact supernatural body.
The gap between cute mode and intense mode is exactly what makes this two-tailed companion so wildly unforgettable.
7. Pen Pen – Neon Genesis Evangelion
Warm-water penguin living inside a fridge instantly sets Neon Genesis Evangelion apart from anything else on television.
Apartment life gains a strange rhythm as Pen Pen shuffles around like a grumpy roommate who pays no rent yet somehow commands total respect.
After long days filled with existential dread and mech battles, a quiet return home with a penguin waddling across kitchen tile brings an unexpected sense of comfort. Weird, wonderful, and oddly relatable.
8. Tony Tony Chopper – One Piece
Eating a Devil Fruit turned Chopper part human, and somehow he still comes across as the most purely innocent soul on the entire Grand Line.
Serving as the Straw Hat crew’s doctor, this reindeer shifts between adorable and formidable depending on what the moment demands, an impressive range for someone wearing a tiny pink hat. Bad moods rarely survive once Chopper is on screen.
9. Puar – Dragon Ball
Devoted companion stays by Yamcha’s side from the very first arc of Dragon Ball, quietly loyal through every twist and every loss.
Shape-shifting blue creature holds the ability to become almost anything, yet consistently chooses to remain small, soft, and close to a friend who needs backup. Steadfast presence feels like a morning coffee in Dragon Ball, easy to overlook yet impossible to imagine the day without.
10. Totoro – My Neighbor Totoro
Standing at a rain-soaked bus stop holding a leaf over his head, Totoro turned a simple scene into one of the most iconic images in animation history.
Studio Ghibli’s beloved forest spirit brings a calm, protective presence to the film’s childhood world.
Totoro never speaks a word, yet somehow communicates everything about wonder, safety, and the magic tucked inside ordinary childhood moments.
11. Doraemon – Doraemon
Arriving from the future with a magical pocket full of gadgets, Doraemon immediately became something generations of kids wished they could have for themselves.
Equal parts robot, cat, and life coach, an earless blue companion helps the perpetually unlucky Nobita navigate school, friendships, and the occasional time-travel disaster. Running since 1969, the series makes Doraemon one of the longest-standing positive influences in anime history.
12. Jibanyan – Yo-Kai Watch
Jibanyan is a ghost cat whose comic obsession with challenging trucks grows out of his emotional backstory.
Born from the spirit of a cat named Rudy, Jibanyan carries real emotional backstory beneath all the slapstick chaos, which is a combination that hits surprisingly hard. Catching a Yo-kai Watch episode on a quiet afternoon feels like snacking on something you thought was just sweet but turns out to have real depth.
13. Keroberos / Kero – Cardcaptor Sakura
Plush toy energy shows up first, then a centuries-old guardian immediately starts bossing Sakura around with complete authority, like he has been waiting years for someone to finally listen.
Tiny stuffed-lion exterior clashes perfectly with the oversized ego inside, turning every scene into something sharper and funnier, especially when that confidence starts running ahead of reality.
Companion like that critiques every snack choice with zero hesitation, delivering opinions nobody asked for but somehow always hearing. Late nights still find him sticking around, helping prepare for the next card battle without ever considering leaving.
14. Plue – Fairy Tail
Nobody fully understands what Plue is, and that is a significant part of the charm.
Originally from Rave Master and later reintroduced in Fairy Tail as Lucy’s Canis Minor spirit, this little round creature communicates entirely in “puu” sounds and still manages to feel like a trusted friend. Plue is proof that you do not need dialogue, backstory, or even a recognizable species to become someone’s favorite character on the roster.
15. Mokona – Tsubasa: Reservoir Chronicle / xxxHOLiC
Looking like someone designed the cutest possible travel pillow and then gave it a personality, dimensional teleportation powers, and absolutely no volume control, Mokona immediately stands out.
Mokona acts as an interdimensional guide in Tsubasa and a familiar-like presence in xxxHOLiC, giving CLAMP one of its most distinctive mascot figures. More power sits inside that red gem on the forehead than in most characters three times the size, which is a very Mokona way to operate.
