Troka is an extrovert, They love meeting new people and talking to others! While technically being an autobot, they don't really care for the war (especially being a child and all), so they really make friends with anyone.
Before
Before Troka was an Autobot, They have barely any history. It's hard to find anything on them from before they randomly appeared, with no family or links. Although they have, supposedly, worked in the divine since their creation as the Demigod of Nature. They're Shamble's assistant, and work in a garden.
Joining
Troka was found by the Autobots in the middle of no where, looking at flowers. They were of course taken back to the Ark, and then adopted by the Autobots. They were later adopted by Starcrash, along with Jetstorm and Typhoon, and have little to no relation to the war.
