Ok so... Giga and Mega make up Overlord... Giga being the tank/legs and Mega being the Jet/tophalf. Well I had an idea...

Mega and Giga, before the war, were duocons who turned into Overlord when combined. Mega was the more crazy and hyperactive one, while Giga was the calm and collaborative one. They were used by the functionalist government as an ultimate weapon that just ended up failing. So, like anyone would do, they basically threw them in the trash, that trash being Kaon city.

They only had each other and to them, that's all they needed. Through these hard times it brought Mega and Giga closer to each other. They knew they were stronger together in the literal sense, using this strength to fight in the gladiatorial pits of Kaon as Overlord. Everyone feared Overlord but never knew who they really were, and that's how they wanted it. Giga didn't want anyone finding out about them being Overlord. He wanted Overlord to be who they are. This made it very hard because Mega wanted to tell everyone who they truly are and show that even if people are small, together they can make a difference. Giga really didn't like that and basically forced Mega to stay as Overlord for the rest of the days before the war started.

Megatron was the only person Overlord couldn't take down, but when Megatron asked them to join they didn't skip a beat. Giga tried to keep the facade going, but Mega just couldn't take it anymore and uncombined with him. Mega believed in the Decepticon cause, but couldn't handle not being herself.

When "Overlord" didn't show up when he was called, Megatron got suspicious. Megatron finally found Mega and Giga arguing over if they should stay as Overlord or go their separate ways. He didn't like that one of his strongest warriors was going to be gone just because of them not getting along. So, he took this into his own hands.

Mega tried her best to leave, but Megatron started hurting her everytime she tried to move. Giga didn't fight Megatron and actually opened his arms to the punishment "he deserved" for coming uncombined. This is when the sick and evil parts of Megatron really show. With these two, he didn't care anymore about losing one of his strongest warriors, he just cared about showing people what happens when they don't listen to him. He took the two out into a rally of Decepticons and gave his whole speech about what happens to traitors yata yata. Then, he carefully went over to Giga, who's wide open with his spark exposed, and ripped it out. Throwing the body of Mega's one and only friend/soon to be spark mate, next to her. Shockwave, the one holding Mega, forced her to immediately combine with the dead corpse of Giga. The brain module of Giga was still slightly functioning and when Mega combined it powered his brain more giving Overlord still the brain process and thoughts of both Giga and Mega. But, Giga losing his spark was where the real torture begins. Mega's brain and everything had to go into overdrive for Giga to also power Overlord's "second half". This caused Mega to get driven insane by the thoughts of her dead partner running through her brain. The two parts basically became one being. Another factor that caused them to become one was they almost always needed more energon almost immediately. This energon was shared with both parts of the body. One last problem this also introduced was the fact that Overlord transforming into the Jet and Tank for an extended period of time could cause, what was once Giga, to become fully incapacitated. Giga's brain module would stop functioning, completely shutting down all parts of his body. So, technically, Overlord wouldn't exist anymore because,well, no legs and no second brain. So, it would just be Mega herself (still messed up though and definitely having a multiple personality disorder). This also leads to the fact that when in Tank and Jet mode they can't be far apart.

Ok... this was a lot, but u still might be wondering, wouldn't Giga be in the after spark? Well yes silly goose. This is actually how Overlord can talk to anyone in their heads and astral project himself. Overlord can reach all other cybertronians through the allspark, but their physical body can't reach others. So it's either a projection or thought in others' heads.

Her in all her glory
