Transformers: Robot Masters
A member of the Cyberjet Battalion, Delta Seeker was friends with X-Gunner before the latter defected to the Decepticons. Has a number of abilities, including teleportation, and his weapon is called the Arm Gauntlet.
Wings of Honor
When most of the members of the Autobot Elite Guard confronted Bruticus they were nearly wiped out, with Bruticus killing most of the Guard. Dion was able to blind Bruticus, forcing it to separate into the Combaticons, but the Combaticons finished off most of the remaining Guard, including Metalhawk, who was killed by Onslaught. This left only Dion alive, buried in the rubble, and Thunderclash's team, which was off planet at the time.
