Munitia

Once, Munitia was a fierce Decepticon soldier, and while her warrior spark still rages on, her physical prowess has worn away. Suffering from some joint problems, Munitia usually stays back at the Decepticon base/vessel she stationed in, fearing that her condition may get worse. 

Do not let that fool you, As a weapons and flight specialist, Munitia was a warrior to be reckoned with during her peak, killing enemies in a similar fashion to some of Cybertron’s most unethical mercenaries, despite this she is quite cool-headed and friendly towards her friends.

Munitia also likes a good alt-mode, recently adopting a human vehicle called a HISS tank as one.

History:

Munitia was forged during the early Sentinel prime era and joined the Decepticons early on in her life. During the great war she was a fierce soldier. She also fought during the battle of Vos against Scorn and Scarr[Spotlight Scorn]

However over time for some unknown reason her body started to deteriorate, and she started to develop joint problems. She started to stay in the bases she was stationed in, as she feared her condition would get worse.

She became Gigatron tactician, and was with him when he went to earth, with her and Viper avoiding capture as they stayed back on the ship. She was helping Cobra on their M.A.S.S device when she noted that a spacetime event caused the machine to malfunction.

Unbeknownst to her, this was caused by Croc master teleportation[Arrival of Croc master]

Notes:

She’s based on G1 Munitia

The Vengeance war happened during the G.I.Joe-Cobra war, so having a HISS tank mode is explainable since he could have scanned one, or a scanning probe could have also gave his mode as well.
