I remember that Silas/Breakdown fired his cannon in vehicle mode. I also think Starscream can fire missiles, and I believe the Jet Vehicon fired a his blaster as a jet.

The toy of Ratchet can deploy his swords as a vehicle. Most of the Cyberverse toys have weapons in vehicle mode.

Anyone else?

 

I'm pretty sure Knockout was shooting at bumblebee in Speed Metal

 

He was but that specific firearm is probably only usable in vehicle mode because we've never seen him shoot in bot mode, other than the resonance blaster. I also assume Megatron can use his arm cannon in jet mode but he seems to prefer basic pew-pew dogfights.

 

Vehicons, Breakdwon/Sylas, Megatron, Bumblebee (I think), Starscream, Laserbeak  p), & Dreadwing

 

all the flyers can shoot including soundwave. knockout and breakdown as well but I don't think any others can though lol

 

I think they all can if they wanted to

 

Optimus should, like, deploy his arm in vehicle mode, wielding the Forge.  

 

So far, only Decepticons have accesses to weapons in vehicle modes.

That actually has been on key characteristic that differentiates Autobots and the Decepticons in many TF continuities. Decepticons, most if not all of them take military vehicle forms, while Autobots take civilian vehicles. Making Decepticons more of war machines than the Autobots

 

Also of note, it appears Insecticons can only fire their weapons in bug mode.

 

It's possible some Transformers have alternate weapons in vehicle mode (similar to the Cybertron games), though most aren't seen using any weapons at all in vehicle mode, mainly the members of Team Prime since they use civilian-based vehicles in order to remain incognito.

 

Incorrect. In Orion Pax Part 2, Tunnel Vision and most prominently in Toxicity, an Insecticon in robot mode has deployed a blaster from their arm. It's more subtle than other robots, but its there.

 

He was, makes me wonder what car Knockout scanned that had a concealed blaster in the back.

 

Wheeljack should use his swords in vehicle mode. Have them flip out from underneath him and look like his toy.

 

Megatron can fire in vechical mode

 

Well, the commercial for the Weaponizers mentioned they can be usedin vehicle mode... as much as a commercial is part of a continuity.

Transformers Prime - "Weaponizers" Commercial - YouTube

 

and it's also animated.

I wonder if we'll ever see that in the show?

 

Starscream (Our of his Head)

Vehicons (Darkness Rising Part One)

Jet Vehicons (Inside Job)

Megatron (One Shall Fall)

Knock Out (Speed Metal)

Breakdown (Deux Ex Machina)

Soundwave (Triage)

Skyquake (Master and Student)

Insecticons/Hardshell (Toxicity)

I don't think we've seen any Autobots use vehicular weapons. Yet all the Decepticons seem to be able to, though we have yet to see Dreadwing display this ability.

 

i think most of them can! hence the weaponizer toys

 

Dreadwing used his vehicle modes machine-gun/pewpew blaster in Triangulation, when he attacks ApexStarscream  

 

Since the Deluxe Cliffjumper toy comes with a mace weapon, I'd guess if he had lived we would have seen mace-hands.

Bumblebee has not displayed a melee weapon in the show, but one of his toys, and the Capsule Micron have swords.

For the purposes of my Transformers Prime RPG, I'm giving them Cliff mace-hands and Bumbebee sword hands.
