You were part of the Decepticon’s and the Nemesis ship with Lord Megatron, Starscream, knockout, breakdown, dreadwing, shockwave, soundwave, Predaking, Arachnid and The Velicons, but after a couple of cycles in, you started feeling strange, eating weird metals, hard to transform into your alt mode, getting dizzy and nausea on the battlefield against the autobots, drinking lots of Enegron and one time You tried drinking dark Enegron which Megatron stopped you in time
Something was wrong, you took the scanner from the medbay in secret and after scanning yourself in your quarters you found out you were sparked and the results said it was Megatron’s…you were scared to tell him directly because you don’t know how he’ll react, so you decide to keep it a secret until then, but during your times and cycles…you kept getting emotional, purging, using the groundbridge to head out to the location you were needed at which took forever instead of flying/driving, and same routine, soon Lord Megatron, Starscream, knockout, breakdown, dreadwing, shockwave, soundwave, Predaking, Arachnid and The Velicons were either getting suspicious of you or worried for you or just ignoring…but you knew the truth and you tend to keep it that way
