Here's another shot of the Lightning Cruiser but with the Red Ranger in it.

Storm Blaster used its hooks to grab onto Dreadfeather while he was in midair and Lightning Cruiser in Flight Mode fired at Dreadfeather which destroyed him.

NOTE: Blue Senturion was shown in the ep briefly but he did not fight.
Dreadfeather didn't grow. There was no intention of him growing since he wasn't shown to have the special food.
