I see Dynamax as my dark half and Datamatrix as my light half.
Dynamax has become twisted due to the losses and suffering he has been through and it's made him into something of a monster. Something I can relate to, my teen years.
Datamatrix is my fun side, my happy side. The guy who'd prefer to kick his feet up, relax and have fun rather than deal with all of his problems, but when he does, he does it well and does it right. Plus he's also symbolic of my relationship with -Soundwave-. If I need to explain then you don't know the lady well then do you?:P
Data's casettes are my imagination run wild. After all i have a viral Condor who has a feud with the light fixture in his master's room, a narcisitic bat who makes Tracks look tame, a drone like superwarrior and a pair of Mexican dinosaurs.

Nemeis Jetfire represents me having fun with my friends. He exists as a joke towads Venomous Prime and his disdain for the Jetfire name, exibited by Datamatrix's involvement in his naming.
Omega...that's my cliche side. You know the type of character that appears weak and unasuming but eventually changes into a terror the likes of which the world has never seen? that's this guy....plus my fanboyism of Cell from Dragonball Z. Wait until I show you why (as soon as Glyph solves the alt rotation problem that is). No Omega isn't going to absorb Hot Rod and Arcee to attain his final Perfect Form....nothing like that. It's more "in the spirit of..".
Dreadknight and Dynabreaker are symbolic of my friendships too. Tammuz is Dread's co-creator (made his look and inspired his bio) and TS based 'Breaker off of my backstory, and i took her in when he needed to make some room.
The others...nothing too personal.
