- —Seal to Jason (Service Unavailable)
Seal Vladaam is a main character in the machinima Sandguardians. He first appeared in Welcome to Sandbox! very briefly and again made another brief appearance in Reese's Pieces. Seal made his prominent appearance in Strange Encounters with a much larger role.
Seal seems to be a very brave soldier and the most mature character in the series. During the flashback in Episode 10, he is revealed to be trustworthy as he stood by McGrath while they were under attack. As the two became overwhelmed, Seal wanted to stay with McGrath, despite being told to leave while in possession of a powerful piece of equipment, but McGrath pleaded him to escape. Seal did so and promised McGrath that he would come back for him, an action that has haunted him from that point on.
As a result of this, Seal has shown to become very rash in his actions, specifically when they concern McGrath. For example, in High in the Sky Seal was impatient and eagerly wanted to go investigate the Phantom, disregarding the dangers that it may hold. He revealed in Service Unavailable, that he disbanded his objective of going to the Guardian rendezvous meeting to go rescue McGrath at his old lab. Unfortunately, his plans went awry as his ship was attacked and the incident led to the death of his pilot, and fellow Guardian, Goon. With Goon's help, Seal managed to escape on a Banshee but eventually crash-landed in Sandbox. In Insight to the Past, after viewing McGrath's video message, Seal desperately wanted to go rescue him, believing that his friend may still be alive. Seal went so far as to make Nash feel guilty by stating that McGrath loved her and it would be wrong for her to not want to go save him, in order to save his friend.
Seal has also shown a great deal of respect towards his comrades, whether they like him or not. For instance, although Legend and Ichabod do not trust him, Seal still managed to show a respectful and calm attitude towards them.
Seal may have experience flying Covenant vehicles, as shown in Episode 1. Seal also has incredible skill in stealth & strength, as he was able to survive a blast from a Guardian Tower, & 2 grenades from Dax. During all this, he remained unseen from the other soldiers. In High in the Sky, Seal displayed superior fighting skills, being able to battle and eliminate a Hornet by himself.
Seal seems to have a very friendly relationship with Jason, as the two managed to talk with each other in Episode 9 and in Episode 10, Jason stood by him throughout his story. Of all the soldiers in Sandbox, Seal seems to respect Jason the most.
Seal and Dax also have a very friendly relationship with each other. On most occasions, Dax seems to always agree with Seal's ideas, seeing him as heroic and adventurous; one can say that Dax admires Seal in a way and sees him as his answer for a better purpose. Dax may also see Seal as a celebrity or authority figure, showing concern when Seal is unhappy.
Seal seems to have history with Nash, much like McGrath. He explains that Nash would never to a friend and shared similar motives with him and McGrath as well. Nash also refers to Seal as "Chameleon", further displaying their history as friends. Also, much like McGrath, Nash seems to understand Seal's native language.
Seal and McGrath seemed to be very close friends, as McGrath was able to talk with him perfectly. The two also seem to respect each other to a very high degree and would risk their lives with one another. Seal revealed in Episode 21 that he abandoned his trip to the rendezvous in order to rescue McGrath, but this plan ultimately failed.
After viewing a video message from McGrath, where McGrath confessed his honor with collaborating with Seal, Seal desperately wanted to go rescue him, yet again abandoning his mission to the rendezvous. He also persuaded Nash to come along and went so far as to make her feel guilty, calling her selfish. Seal also seems to feel guilty for being unable to save McGrath and his actions have been greatly affected by said guilt.
Legend did not trust Seal during his first encounter with him, but managed to provide him with an escape route out of Sandbox. Seal replies to Legend with a thank you. It is currently unknown if Legend trusts Seal.
Seal and Ichabod did not have much interaction with each other. Icky did not trust Seal during their first encounter and quickly made a plan to assassinate him in Another One Down. During that time, Dax and Jason decided to assist Seal on his mission, but Icky did not join them, feeling that Seal was dangerous. Icky's current opinions towards Seal are currently unknown.
