  We present the ultrarelativistic boost of the general global monopole
solution which is parametrized by mass and deficit solid angle. The problem is
addressed from two different perspectives. In the first one the primary object
for performing the boost is the metric tensor while in the second one the
energy momentum tensor is used. Since the solution is sourced by a triplet of
scalar fields that effectively vanish in the boosting limit we investigate the
behavior of a scalar field in a simpler setup. Namely, we perform the boosting
study of the spherically symmetric solution with a free scalar field given by
Janis, Newman and Winicour. The scalar field is again vanishing in the limit
pointing to a broader pattern of scalar field behaviour during an
ultrarelativistic boost in highly symmetric situations.
