I know his voice is supposed to sound different but he sounds so goofy when you use voicelines and communication lines such as “Hello!” and “Understood”. It gets really annoying after a while for me personally. It’s like a mix between his default voice and the actual voice you’re supposed to hear with the skin.
When you hear him interacting with other heroes before a match begins he still sounds different from his default voice, but he sounds so much cooler and not like R2D2.
Edit: Now that I think about it I suppose it’s not bugged and the reasoning behind the odd voice is in the Transformers movie Bumblebee uses the radio to try and talk with the humans, and it sort of sounds like how Bumblebee Bastion sounds? If that is the case then I guess that’s a cool detail and I don’t mind the voice as much.
