Tezuka character list bio: Number 26
[b]
- He is a kid who is very knowledgeable about Metro City. He may hold a clue to solving the mysteries of this game. This character is thought to be a representation of Osamu Tezuka himself. In the manga, “Captain Atom,” Astro actually plays a side character, while Alejo plays one of the main characters. There is even a scene where a battle between Astro and Alejo takes place.[/b]
Alejo, along with a few other dudes, is a member of the “School life” grouping of characters. Astro’s always been subjected to the misery of public schooling in his life, both to learn more about the human world and to provide a point of relation for the Japanese elementary/middle schooler target audience - as such, he’s given a couple recurring friends for whenever a school-related story pops up.
Alejo’s original name is Tamao Oume, AKA Tamako, he’s the go-to nerd of the group, and his nickname’s presumably meant to be a play on “Tamago”, a Japanese omelet, in reference to his large egg-shaped glasses. He’s most often seen getting picked on and bullied by the school tough guy, but he and Astro immediately kick it off, which helps alleviate the heat on him a bit. Having a super-powered robot buddy tends to help when getting beaten up.
From what I hear, Osamu Tezuka had a bit of a rough school life, getting bullied for his shrimpy build and wavy hair, so I can buy the whole representation thing. As for Tamao’s appearance as Alejo here, however, he gets it significantly easier than he did in the past. He’s something of a gadget-maker in the 2003 show, with the anime link up there showing off a sick flying bike he made, and generally speaking his life is no longer abject misery. The fact that the bully gets made into a dumb member of the friend group and bastardized by the questionable dub helps a bit too.
Moving on, the bio’s assertion that he “holds a clue” is really really overblown and also not at all relevant at the current time, so just ignore it.
The reference to “Captain Atom”, however, is quite interesting. Captain Atom (originally known as “Ambassador Atom”) was basically prototype Astro Boy before he kicked off his own series.
It had a bit of a weird plot, involving a bunch of denizens of an alternative Earth escaping on a bunch of country-specific spaceships before their planet exploded, wandering space for a bit, and then ending up near our Earth after a while. The only difference between anti-earth people and regular-earth people was their overly large ears; otherwise, each and every person had an exact double from the other earth. Tamao was a dude on the Japan ship who ended up going off on his own and crash-landing on earth, before getting captured by an unscrupulous buisnessman and made to entertain a large audience by fighting a freshly-made Atom in a series of contests. It’s this fight the bio refers to, but it’s probably a good thing they didn’t include the pages themselves, because to make him look stupid, Tamao gets dressed up in a dumb hat…and blackface. Here’s links to two pages depicting the battle if you really want to see it, obviously 
if you didn’t catch that.
The story ultimately ends with the space people coming to live on our Earth, overpopulating the place, starting a war for resources, and then finally having half the old Earth and half the new Earth people move to Mars. It’s a little rough around the edges, but still, if you want to read it you can do so HERE.
Alejo’s always more of a supporting character, and as such doesn’t appear or do all that much, but it’s cool that the game hides smaller and one-off characters like Alejo around the environment for you to find.
