Blue Armored Grub

The Blue Armored Grub, also known as Blue Elite Grub, is a Grub enemy in Plazma Burst: Forward to the Past that is more powerful than its basic counterpart, but less powerful than its more advanced version. Like the other two Grubs, the Blue Armored Grub is harvested by the Human Soldiers on Mars for fighting, but for some reason it fights Humans instead of protecting them. The Blue Armored Grub was introduced to the player in level 5 of the Plazma Burst: Forward to the Past campaign, and then appears in levels 6 and 7, at which point it is replaced by the Red Armored Grub.

These Grubs are completely silver and gray other than some spots of blue along with their red visor. They have a silver mouth guard with some slots for speaking although what they actually say is unknown. They have a similar backpack to the original Grub, but it has blue lights instead of red and no antenna. Visually, the Blue Armored Grub is almost identical to the Red Armored Grub with the exception of the head and some coloring. Compared to their lesser counterparts, this Grub has much more armor and can survive heavier attacks.

Arm Cannon
It appears that this is the only weapon that any Grub can carry. The Blue Armored Grub is seen carrying dual single-shot versions of the Arm Cannon in the first levels where it is seen, and is then later seen carrying Rocket Launchers in level 6 and the Ray Rifle TCoRR in level 7.

Trivia

 * Both of the Armored Grubs seem to be meant for fighting, unlike their weaker counterparts.
