Firefang and Delta Pelagornis
Firefang is a Decepticon hunter, who specializes in searching for non affiliated cybertronians to either convert them to Decepticonism, or eat them. He’s a nasty mofo.
Delta Pelagornis is a neutral with amnesia. He had crashed on a younger Earth and took on the form of pelagornis sandersi. After a storm knocked him into the ocean he lost pretty much all of his memory and became a plane. He was named by his three human friends and he loves to sing.
