First Appearance: TBFGK 3
In his first appearance, he was about to become the (literal) target of a prank by one of the other henchmen that perhaps would have killed most units. Wanda's desire to get "as far away from (him) as possible" when she encounters him holding a target-patterned parasol suggests that this is a recurring pattern. Wanda promoted him to lackey in attendance for Lord Hamster, much to Stanley's amusement,Erf-b1-p028 but this Fateful decision would serve not only to ensure the victory of Gobwin Knob, but possibly save Parson's life.
During the following Turns, Bogroll attempted to assist Parson, by finding him boots (they might be greaves), answering Parson's many questions (which often confused him), constructing a curraiss (with built in pauldrons, and Parson's Hamstard 'heraldry' painted on the front). He also connects the pieces of Parson's Sword together.
Just before the end of the siege, disguised as Parson, Bogroll ambushed and croaked Prince Ansom under the guise of surrender before being croaked himself.Erf-b1-p131 and Erf-b1-p132 Bogroll levelled up twice for this encounter, but was croaked by the fall. Sadly, there were insufficient remains for Wanda to decrypt him the following dayErf-b1-p146, and so Bogroll hopefully passes into the City of Heroes.
Bogroll was intensely loyal and devoted to Parson. Bogroll claimed that his greatest wish would be to save Parson's life. Parson became fond of Bogroll, though he found interaction with him awkward. Bogroll's death in combat played a major role in Parson's eventual decision to discard his Sword of Ruthlessness.
Bogroll seems to have a very high loyalty, especially to Parson.

Bogroll survived a fall that killed a warlord of a much higher level than he was (such that Bogroll leveled twice). This might mean he had a relatively enormous number of hits, or simply that the warlord was injured from earlier events in the siege. Bogroll may also have landed on Ansom.
Another possibility is that Bogroll only survived longer than Ansom because Ansom hit the ground first... and he leveled twice in the moment before he too hit the ground.
It's also possible that Bogroll was able to strangle Ansom before they both hit the ground.
Yet another possibility is that as a Heavy he was more resistant to damage from falling.
The creation of Parson's cuirrass and boots may be an example of Fabrication. The forging of Parson's blade could also be considered an example of this, but it is also possible that anyone could have assembled the sword, as nobody else had been depicted trying.
