Scott Jorgensen’s collection mixes vivid color with darker outlines: a sun-like design on his left shoulder, varied imagery on his right arm, and an octopus across his left side. In a 2013 Fighters Only interview, he said he began with small Japanese symbols in college, then added a leg dragon and a wrist piece. At the time, he estimated more than 45 hours on each arm, about nine on his chest and six and a half on his ribs.
The sun design on his left shoulder

The close-up shows a dark center on Jorgensen’s left shoulder, edged in red and surrounded by yellow-orange rays. Blue and green areas continue into the sleeve. Body Art Guru identifies it as a sun within his space-themed arm work.
The circular center and bright rays remain easy to pick out against the surrounding colors. The image shows the design’s placement and palette; it doesn’t establish what those colors mean to Jorgensen.
The colorful work along his right arm

In this UFC photo, Jorgensen is on the right, extending his right arm toward Jeff Curran on the left. Green, red, purple and darker shaded forms run along the arm. A purple face-like shape is visible near the forearm, but the photo doesn’t show enough to identify every figure.
The dark outlines separate the colored sections, even as the arm stretches through an exchange. The glove and wrist wrap hide the lower edge, so this is a useful view of the sleeve’s layout, not a complete close-up.
The robot on his left forearm

Another view shows a boxy robot on Jorgensen’s left forearm, above his left glove. Body Art Guru also identifies it as a robot. Its squared head, round facial details and rectangular body contrast with the circular sun higher on the arm; yellow and purple areas frame the figure.
The wrist tape and glove cover the lower edge, but the robot’s position is clear: it runs lengthwise with its head toward the elbow. Jorgensen described the broader time he had spent on the arms in the Fighters Only interview, though that doesn’t provide a session-by-session timeline. For a different fighter’s coverage, see Alessio Sakara’s tattoos.
An exchange with Jeff Curran

Jorgensen bends forward in this exchange, with his red-and-black hair visible. Curran is beyond him in blue shorts, and a gloved arm crosses the upper frame. The angle and movement make the shot more useful for the bout context than for tracing the sleeve.
Jorgensen is the nearer fighter with red tape; Curran is farther back with blue tape. Keeping the full frame helps identify whose arm is whose.
The result photograph at UFC 137

In the UFC 137 result photo, Jorgensen stands on the left in a white shirt, the referee raises his arm in the middle, and Curran is on the right in a blue shirt and cap. The clothing hides most of Jorgensen’s torso, leaving the arms more visible.
The MMA Junkie pre-fight interview below is from ahead of UFC on FOX 9. It adds another view of Jorgensen, but it isn’t a tattoo tour or an explanation of the designs.
