Color-Coded for Your Convenience: Incorporates more purple into his wardrobe later in the series as he gradually becomes more Greeed-like.

He does this even when transforming into Birth.

To a limited extent, his henshin pose of slashing his arm downward.

Also, him saying ' SEIIIIYAA!' during finishers.

Holding his hands out like a tiger in Tatoba and Latorartar forms, or really any forms with the Tora Claws.

Catchphrase: ' Seiya!' during his Early-Bird Cameo in Kamen Rider W Forever A To Z The Gaia Memories Of Fate he says 'Riders should help each other out', which seems to have become his Catch Phrase for crossovers.

Character Development: Goes from a lonely wandering vagrant who's spurred on by pure Chronic Hero Syndrome to a hero who truly learns to resolve for himself again and accept the help of those around him.

Now remember the kind of emotional baggage Riders from the Showa Era had to deal with and really think about this for a second.

Broken Hero: Very much in the front running for being quite possibly the most broken Rider in the entire franchise.

Beware the Nice Ones: #43 shows how scary Eiji can be when he is angry.

Fortunately he managed to return to his true self come next episode.

Baleful Polymorph: Is forced into fully transforming into a berserk, mindless Greeed by Dr.

All-Loving Hero: He's very selfless to the point of helping others when needed and he will risk his life to protect the ones he care for.

Voted #1 Kamen Rider in the Kamen Rider OOO franchise, #4 Kamen Rider in the Heisei era, and #4 Kamen Rider overall in NHK's All Kamen Rider Popularity Vote. A world-traveling vagrant with no family, dreams, or long-term career, whose recent stint as a museum guard for the Kougami Foundation ends with him taking possession of three Core Medals and the OOO Driver, allowing him to turn into Kamen Rider OOO and fulfill his subconscious impulse for helping people.
