Arsenal Force

It's worth noting that this didn't even scratch Beast Wars Megatron, its target.

The Arsenal Force is a weapon of immense power formed completely from solitarium. It is highly sought after by Starscream.

Toys

Robot Masters

The Arsenal Force is formed from the four solitarium weapons included with the first wave of Robot Masters Decepticons.

• RM-04 Wrecker Hook's "Boost Hammer" (core)
• RM-06 Air Hunter's "Sacred-Cut Sword Armorkiller" (right side)
• RM-08 Wing Stun's "Jamming Trident" (left side)
• RM-09 Psycho Orb's "Calamity Defenser" (top)

100 sets of special clear-red versions of these four weapons were made available as a contest prize, second place in the same contest where Cybertron City was first prize.

Also, each of the mail-away "Limited Black Version" Robot Masters toys came with a chrome-gold version of one of the four weapons.

• RM-01 Optimus Prime - Gold Calamity Defenser
• RM-02 Megatron - Gold Sacred-Cut Sword Armorkiller
• RM-11 Optimus Primal - Gold Boost Hammer
• RM-12 Starscream - Gold Jamming Trident

Two further solitarium weapons were released. They were never shown to have a definite combination with the existing Arsenal Force or even with each other, but all six can be combined with some ingenuity.

• RM-13 Smoke Sniper's "Radial Pod"
• RM-14 Gigant Bomb's "Pulverizer"

Additionally, while not technically a solitarium weapon, the nameless missile launcher included with Optimus Prime, Megatron, and Optimus Primal (and their redecoes) can also be added into the mix if you're feeling like it.

Also of note is that the extra chromed weapons from the first Robot Masters Autobots are the same transparent plastic as the solitarium weapons underneath the chrome coat.

Trivia

• It has been speculated that the six solitarium weapons are actually unused accessories from the Takara "LED Powers" Microman series, which was abruptly cancelled in late 2000. The last section of the line included transparent plastic weapons that could be combined to form armor or larger weapons for the individual Microman figures. The handle size is also identical between the solitarium parts and the "Shining Tector" Microman weapons.
