- In Sly 3 and Thieves in Time, the wheelchair is shown to be practically indestructible or at least extremely durable, as when Bentley dies while out in the field, he falls out while the chair remains unscratched.
- Bentley’s wheelchair appears to have computers and a red button attached to it, presumably used for utilizing gadgets built into his chair. They are no longer present in Thieves in Time, being replaced with an interactive holographic display.
- When conversing with his teammates through the binocucom in Sly 3, Bentley’s image in the binocucom will now show his upper body instead of being close up to his face. This is due to his binocucom being a built-in function in his wheelchair that can mechanically appear on the arm of his chair. This also occurs in Thieves in Time, despite the implication that he is using a regular binocucom.
- Due to being in a wheelchair, Bentley is the playable character in the transition between Sly 2 and Sly 3 that received the most changes in terms of animations.
- While standing still, Bentley will look around with a more neutral expression; in Sly 2, Bentley will look around with a more alert and cautious expression.
- Being in a wheelchair will now cause Bentley to stand diagonally while on inclined surfaces.
- His previous double jump in Sly 2 has him perform a somersault in midair before being replaced with his wheelchair’s jet engines.
- He receives a new idle animation that has him perform a wheelie with his wheelchair.
- When activating power-ups in Sly 3, Bentley will press a red button on the arm of his chair instead of pulling the trigger on his crossbow in Sly 2.
- When knocked back by enemy attacks or hazards in Sly 2, Bentley will tuck into his shell while flying back, sometimes causing him to bounce upwards into the air; in Sly 3, he will simply get knocked back and shake his head upon landing, reducing his vulnerability time.
- His previous death animation in Sly 2 has him jump up into the air and fall on his back while the one in Sly 3 has him fall onto his stomach.
- His new death animation when getting crushed has him get flattened, unlike in Sly 2 where he falls over on his stomach.
- Bentley’s new falling animation has him suddenly look down as his wheelchair falls down into a bottomless pit, then tucks into his shell as he follows afterwards, with his helmet flying off in the process; in Sly 2, he flaps his arms before tucking into his shell, plummeting to his death afterwards.
Although the wheelchair and its capabilities do in fact make Bentley significantly more mobile and stronger while operating on the field, he does have additional weaknesses and limitations as a result of being confined to a wheelchair. For one, he is no longer able to sneak across buildings or crawl under tables or tight spaces; this bars him off from accessing certain areas while the latter also eliminates a possible hiding spot from guards. None of the mechanical innovations in his chair grants Bentley the ability to swim, and thus he will still drown upon falling into water much like before.
If Bentley is separated from his wheelchair, he is essentially rendered helpless due to his paraplegia. Octavio and LeFwee took advantage of this by knocking him off of the wheelchair, and his death animation in Sly 3 and Thieves in Time also has him fall out of the wheelchair. Octavio also once held Bentley hostage by picking his wheelchair up, implying that Bentley has to be in control of his wheelchair for it to function.
At the end of Sly 2, the Cooper Gang and Carmelita Fox agreed to a truce to confront Clock-La, an amalgamation of Neyla and the body of Clockwerk. Clock-La was eventually rendered unable to attack after Murray pried open Clock-La’s beak so that Bentley could remove the Hate Chip. Unfortunately, the beak closed shut just after Bentley removed the chip, crushing him. A distraught Murray freed Bentley from under the beak, at which point Bentley stated that he was unable to walk. After he and Murray helped Sly Cooper escape captivity after the truce, Bentley was checked into the hospital for treatment, receiving a wheelchair in the process. After Sly and Murray broke into the hospital to retrieve him, Bentley upgraded and modified his chair so that he could still be a secondary field agent to the team. He still uses this chair to date, upgrading it further through personal upgrades and ThiefNet.
