Astro (2003)

Anime series

Full Timeline

- Canon compliant, taking place in a futuristic 2003. Canon deviations begin after the end of the show.
- Astro continues being a hero to both humans and robots, however the conflict between them will never be 100% resolved. As is nature.
- 2018 (15 years), Dr. O'Shay passes away to age, however Reno graduates with a robotics degree. Without the Doctor to do my repairs and vouch for me, Reno takes up the task, and we remain close friends.
- As more advanced robots continue to be created, I am frequently offered upgrades, which I decline, preferring to remain the same. Zoran, who's still always around, makes the same choice.

.

- 2053 (50), newly built robots begin to consistently surpass me in power, it becomes a battle to remain relevant. A point is reached where any upgrades, had I ever accepted any, would only help me compete for a few more years. Only stubbornly wanting to help no matter what keeps me in the game.
- 2078 (75), technology exists to dodge death by having consciousness and memory uploaded into robots. Reno pioneers by being the first human truly fully resurrected in robot form. He remains my and Zoran's friend and mechanic.

.

- 2103 (100), my final mission is a rough one that nearly leaves me trashed, fortunately Reno fixes me. But this, the expense of replacing such old-by-now parts, and his and Zoran's concern, is enough to finally convince me to retire from actively hero-ing.
- Being important to human and robot history, historians are willing to pay to keep me and Zoran running even though I've retired. We now simply live about Metro City, being walking museum pieces. We're especially popular with kids, considering we still look and sound like kids ourselves.
- We love to give history lessons, which usually center around our adventures, how we've helped both people and robots, and how important it is we all get along.

.

- 2128 (125), while being wandering museum pieces, we still occasionally help fight crime within the city, but greater robots are handling greater threats now.
- Reno moves off planet to study and bring his work to other places in greater need of him.
- 2153 (150), an unimaginably massive threat comes right to Metro City, prompting me to join the rest of the hero bots in the effort to fight it off. Being less fit for the task and narrowly avoiding being destroyed, I pay the high price of losing the right half of my face as well as suffering other, thankfully, mostly external damage.
- However, materials to replace missing external parts no longer match what I was made with, and despite multiple tries, end up never being fully compatible, so I give up on getting it fixed. I work fine otherwise, anyway.
Appearance below.

- Returning to my previous purpose with Zoran as a walking museum, humans since become less receptive to meeting me due to my wrecked appearance.
However, just as many don't seem to mind and in fact take pity. It gets a bit repetitive.

.

- 2178 (175), we're slowly forgotten by humans despite our best efforts to continue to be appealing to them. Few will take a minute to talk to an irrelevant and seemingly wrecked bot, no matter how human I am, or how important I once was.
- 2203 (200), gradual rust and wear of what insides are exposed finally cause a partial short circuit on a rainy day. The impairment, mostly to ease and coordination of movement, is permanent, due to no one having the time or money to repair a relic such as me.
- Zoran, still being near perfectly intact, has to take up the older sibling role to now look after me instead.
- Now being fairly useless, I become pretty much hopeless, to Zoran's worry.

.

- 2??? (200+?), Zoran and I eventually depart Earth and somehow find home on Qanaxis, but the method of travel is currently unknown.

Gebura

Project Moon

Gebby

- More heroic and compassionate than canon Gebura.
- She arrived at some point, after becoming The Slaughter (TMA), to be a protector of Metro City from evil.

- Came on missions with me sometimes!!
- Ran into her a bunch of other times too, throughout my life.

Astro (2009)

Movie

Canon

- Canon more or less matches the following fic: Family is Made in the Heart (LINK)
- Canon compliant, minus the Peacekeeper absorbed Toby instead of vaporizing him, to nobody's knowledge.
- Oops yeah Toby isn't dead, he returns once the Peacekeeper is destroyed, and I find him after being revived by Zog.
- The expected "dad you're insane you replaced me with a metal copy" drama ensues. We're distant and indifferent for months, with me fearing deactivation for a while, since Toby's return makes my original purpose null.
- We eventually mostly sort emotions out with each other and accept each other as brothers. Best brothers, twins even.
- Toby eventually gains cybernetics and we both fight crime together!
- I receive upgrades to match him in height as we grow up. Twins.
- WIP

Yeah sorry there's
spirals again

- Years in the future, what humans don't know to be a Spiral-related relic crashes to earth as a meteorite. It is discovered to be a source of Helical energy, which was previously unseen and unknown to this universe.
- My repeated investigation of whatever it is (I dont remember yet) results in my gradual Contamination.
- Strangely, I'm the most affected, with everyone else wondering what the hell is very slowly going wrong with me.
- It is a possibility that machines (such as robots) are more sensitive to Helical energy than organic things. Especially a machine as advanced as I am.
