Alr, uh, since as of right now, slugterra is winning the poll, and Shadowslugger is the au you guys want information on. Here are some of the tidbits I wrote down.

A slug-slinging competition is help every year, I think that's Canon but whatever.

Kord, Trixie, and Pronto meet at the competition (this completion takes place when Eli is fifteen). None of them made it to the final round, but they made friends.

Kord, Trixie, and Pronto become a little adventuring group, and about 9 months later, they stumble into the place where Will is (I think it was called corrupted caverns idk) they bring him with and he kinda joins their group making the Shane gang once Will has recovered Energy from being in the corrupted caverns. Eventually, three months later, Will Shane is ready to return to protecting the caverns, and he enters the competition to get his name out there to inspire hope. No one really believes that he is who he is until halfway through the competition. Burpy is also with Will. He kind of starts off like Eli did in the series, with only Burpy at his side.

And now to Eli's party of the story.

When Will was sent to the corrupted caverns, Eli was two. Eli's guardian, at this time, I might just say the guardian is Eli's cousin, brings Eli to slugterra to search for Will after he misses the time to visit. A resulting confrontation with Dr Blakk's men results in at least one more missing member of the family. The cousin isn't important, so they might just not re surface, but the important thing is that Eli is captured by Dr Blakk's men.

Eli escapes his capture with a member of the Shadow clan, who had been there longer than Eli. When this happens, Eli is about five.

He is raised by the Shadow clan, but he knows some Human-like slugterrans. He does have a rather close friendship with a human named Anthony
