Headquarters: Underground Lab and House (Size: Large; Toughness: 15; Features: Communications, Computer, Concealed, Workshop, Laboratory, Library, Fire Prevention System, Living Space, Power System, Isolated, Security System 2 [DC 30], Robotic Minions; Equipment points: 18)
Note about Headquarters: House contains library and living space, and is connected to the lab’s security, power, communications, and fire prevention systems. A minor workshop is located in the house, but is not included in the equipment cost as Crusader uses the house workshop to keep visitors from figuring out about the underground lab. The lab is located beneath the house and contains power system, laboratory, main workshop, computer, communications, security system, and fire prevention system. The lab is both concealed and isolated.
Description of Lab: When some heroes state that the lab doesn’t look so grand, Crusader often counters, “Hey, not everyone can afford a giant space-station or Antarctic headquarters!” This is ironic, considering that Samuel is wealthy as sin!
Description of Armor: The armor is a high-tech battlesuit constructed of armor plating, metallic mesh, and ballistic materials of Samuel’s own designs. The metal is a titanium-gold-iron alloy that makes the armor extremely durable while maintaining its weight ratio, in addition to preventing ice from forming on the armor when flying at high altitudes. Originally, the armor was designed to serve as a rescue and exploration power armor; Samuel later upgraded the armor after he saved two children from a burning building. He added offensive capabilities when he decided to use the armor to fight against terrorism and crime throughout the world.
The Crusader battlesuit is equipped with energy-based weapons, ranging from the wrist energy blasters to the energy blade to the arm cannon to energy particle palm blasters, as well as other weaponry such as built-in shoulder rocket launchers. The armor is also equipped with flares that aid in blinding enemies as well as acting as anti-missile chaffs. A sophisticated energy projector is used to generate a protective hexagonal pattern of miniature force fields in front of the wearer; however, the energy shield is ablative, meaning attacks cause the shield to gradually weaken. The reason for this is to conserve energy. Probably due to his reading of comic books, Samuel also installed a low-level neural shield generator that generates a sort of ‘psychic static’ that guards against mental intrusions. The armor is also shielded from electromagnetic pulse (EMP) attacks. The Crusader battlesuit enhances the wearer’s strength, due to hydraulics and servomotors. The helmet provides the communications as well as a sensory shield to protect the wearer from attacks aimed at the senses, in addition to a holographic Heads-Up Display (HUD) and targeting computer. Emergency auto-repair systems ensure that Crusader can keep on fighting, even in battles that would leave other heroes down for the count. The armor’s boot jets enable the wearer to fly through the air, while steering and retrothrust jets in the palms help to stabilize flight. In addition, emergency boosters on the shoulders enable Crusader to quickly avoid attacks by strafing right or left. The armor is calibrated to Samuel’s brainwave patterns, making the power armor useless to anyone else. Life support systems provide protection from dangerous and harmful environments. A built-in air recycler/filtration unit provides unlimited oxygen even in areas where there is little or no air.
To make the armor look more ‘heroic’, Samuel painted it in various shades of blue, gold, and white, excepting the visor, which is made of a brown diamond coated tech-lenses. The visor is non-transparent making it impossible for someone to see who is in the armor. Four antennae stick out from the sides of the helmet.
The armor is powered by a tokamak/stellarator-like miniature fusion generator that produces more energy than the world's largest nuclear reactor and is more than fifteen times greater than the power of a Nimitz class aircraft carrier.

I should point out that all of my characters will be 2nd edition as I find third edition to be too similar to D&D 4e. Yuck!

I went back and removed the Technopathic and Magnetic immunity as I felt that it made him too powerful.

I know that a lot of people think characters who have high Intelligence scores should have the Master Plan feat, but I felt that would take away from Crusader. He is really a character who thinks on the fly, making things up as he goes along. He embraces innovation and quick-thinking.

While watching
Iron Man 2 today, I decided to add Quickness 3 for Crusader's quick thinking. Crusader was inspired by Iron Man, especially the versions from the movie, Armored Adventures animated series, and the anime.

Went back and increased a couple of powers as I was worried that I might have made him weak or something.

(6/24/2012) Went back and organized his powers to make it easier to read.

After I saw Emerald Flame's Gladiator battlesuit build, I thought that I should go and put in the suit's immunity to EMP effects and attacks.

Following JD's advice and looking at his work of my character in 3e rules, I went back and did some work on Crusader.
