REDMOND — Funny, they seem so much like normal teenagers right now.

Aside from the fact they arrived at a Starbucks packed clown-car style into one sport utility vehicle, Danny Buecker, John Barnhart, Austin Remington, Bryce Remington, Josh Kliot and Jeremy Heimfeld, all students at The Overlake School in Redmond, look, talk and dress like typical high schoolers.

Tonight, however, that will change in a big way.

When the Washington Stealth take on the Toronto Rock in the National Lacrosse League Champion’s Cup at Comcast Arena, these typical teenagers will morph, as they have for most home games this season, into the Stealth Green Men.

Stealth fans no doubt have noticed the rabid fans — usually five or six of them — covered from head to toe in bright green body suits.

The Green Men spent most of the season in anonymity. They’d show up at games in street clothes, scout out their seats while they still had unobscured vision — and no, they can’t see very well in those things — then head to a bathroom to change into their rowdy alter egos.

“You put on the suits and are anonymous, and people automatically love you,” said Austin Remington, a senior. “It’s really weird.”

The bathrooms at Comcast Arena are not Metropolis phone booths, but a pretty thorough transformation goes on in there as mild-mannered high school lacrosse players turn into fans who can annoy opposing players with a single taunt.

For most of the season, the Green Men did such a good job guarding their identities that Stealth captain Jason Bloom, an assistant coach at Overlake, had no idea his athletes doubled as the Stealth’s best-known unknown fans.

“I didn’t know about them until not even a month ago,” Bloom said. “I was at an Overlake practice and was saying, ‘Have you guys seen the green guys at our games?’ ”

Austin Remington pulled his coach aside. “You know that’s us, right?” he said.

The coach’s reaction?

“You’ve got to be kidding me,” Bloom said. “I just started cracking up.”

Unfortunately for the Stealth, the Green Men may be available only for a second-half cameo at tonight’s title game. Overlake has a game in Vancouver at 4 p.m., and while efforts have been made to get the game time moved up, that had not happened as of Friday afternoon. The fact that Stealth general manager Doug Locker contacted Overlake’s opponent about adjusting the time shows just how much the Green Men mean to the team.

And to think, this all started as a basketball thing. Nick Di Pietro and a few of his Overlake lacrosse teammates saw the suits online and for $30 had them shipped from China. The idea was to wear them to Overlake basketball games — the school’s colors are green and gold, hence the green suits while rooting for a Stealth squad that wears red and black — but since the group consists mostly of lacrosse players, the Green Men decided to take their act north to Everett.

“We decided, why not?” Austin Remington said. “It would be fun and we could maybe promote lacrosse a little bit by going to the games. It was a much bigger hit than we thought it would be.”

The Green Men have grown to be fan favorites, spending time posing for pictures — Buecker said it took them 20 minutes to leave the Stealth’s last game because of photo requests — handing out high-fives, and, though not intentionally, scaring young children.

“The fan reaction is really cool,” Barnhart said. “Although we have had a few toddlers run away from us.”

In addition to riling up the home crowd, the Green Men specialize in harassing opposing players in the penalty box. Most players ignore the jeers, but sometimes the Green Men get inside an opponent’s head. Last week, one player had a few choice words for the group, while another playfully squirted one of the Green Men with a water bottle. Others just laugh at the strange display on the other side of the glass.

“That’s exactly what we want,” Austin Remington said. “We want to get in their heads.”

But while the Green Men hope to occasionally influence the game’s outcome by distracting the enemy, they can’t always see the game. It’s difficult to see through the suits’ head covering, meaning the Green Men often cheer on a delay.

“We have to wait until other people react,” Heimfeld said. “We can never be the first people to celebrate.”

So no, they can’t always see, but the Green Men certainly have a good time. The next challenge is to keep the good times going. Aside from Bryce Remington, a sophomore, the entire group is made up of seniors who are headed out of state for college.

“I was thinking about that a couple of days ago,” Bryce Remington said. “I’ve got some friends who I know will be into it, but it’s going to be hard to replace the enthusiasm and the drive of these guys.

“But I’m going to find a way, and I’m definitely not going to stop doing this because these guys are gone.”
