Honestly, I think Dorian best corresponds with Marcus Damon (English dub data squad character) I mean he would go up and distract or hit a Digimon if imp mom was in trouble, but he wouldn't try to take on a mega or champion or anything right off the bat. Marcus got every level Digimon for a reason. That reason being he kind of needed to xD 

Now I need to come up with an older wise character to give us information. So I will do this later.
