Her old design (this was back before I started figuring out how to draw transformers and it shows lol)

Some basic info about her:

Echostrike (Revamped)

Designation: Echostrike.

Age: approximately 3 million years old.

Height: 34ft

Femme.

Alt mode(s): Cybertronian jet with turbines in the wings (like Windblade), and a helicopter.

She is the first successful result of an experiment by Shockwave and Soundwave to create "a superior Cybertronian".

After a fight with megatron she leaves the deception cause, however that does not make her a good guy. She is far from that. She follows in Shockwave's footsteps and is a scientist. She regularly experiments on fellow Cybertronians and any sentient creature she can get her servos on. Her favorites are organics.

She keeps the decepticon insignia crossed out to show that she isn't aligned with them anymore, but she doesn't just remove it because she still likes the extra intimidation factor it gives her.

She has a sonic screech ability. She can overload audio receptors, temporally shut down processors, and if she can figure out the right frequency she can even get some bots to enter self destruction sequences.

During her time on her own, she found 4 mini cons, two cyber cats that can transform into speakers and two mini bots that transform into the blasters on her back.
